We do actually have an open ticket for investigating why running DisplayFusion causes the system timer resolution to run at 1ms instead of 15ms. We aren't specifically requesting it in our code, so it appears that some .NET Framework function we're using is doing it. Once we get that sorted out, we'll let you know so that you can re-test this.
Thanks!
